INCANDESCENT GAS-BURN ER.

SPECIFICATION forming part of Letters Patent No. 638,652, dated December5, 1899.

Application filed February 23, 1899. Serial No. 706,544. (No model.)

To all whom it may concern:

Be it known that I, LEOPOLD STIASSNY, a subject of the Emperor ofAustria-Hungary, residing at New York city, in the county of New Yorkand State of New York, have invented new and useful Improvements inLamps or Burners, of which the following is a specification.

By means of this invention a lamp or burner can be obtained which mightbe called nonvibrating" or antivibrating and which is useful forpreserving incandescent mantles against destructive shocks orvibrations, as set forth in the following specification and claims andillustrated in the annexed drawings, in which Figure 1 is a sectionalelevation of a burner. Fig. 2 is a side elevation of a modification.Fig. 3 is a sectional elevation of Fig. 2.

In order to enable those skilled in the art to make and use myinvention, I will now describe the same in detail, referring to thedrawings, wherein- The numeral 2 indicates a Bunsen burner, and 1 anupper burner-section inwardly contraeted to form an annular shoulder 14,which is extended downward in the form of a sleeve 14, telescoping orslidable vertically on the upper tubular portion 2 of the Bunsen burner.The vertically-slidable upper burner-section 1 is provided with agallery 4 for the chimney 5, and from the gallery depends a perforatedcup-shaped ornament 6, having in the form shown in Fig. 1 an orifice 6in its base or lower portion to accommodate the Bunsen burner and thespring 10, hereinafter referred to. The ornament 6 is provided with asetscrew 7, engaging a screw-socket 8 to adjust-- ably hold thewire-support 9, from the upper end of which the mantle 3 is suspended.

The Bunsen burner is provided with a fixed cup-shaped flange 11,surrounding the air-inlets 20, and on this flange rests the lower end ofa spring 10, the upper end of which in Fig. 1 bears against the annularshoulder 14 of the vertically-slidable upper burner-section to form ayielding non-vibrating support for the upper burner-section, whichcarries the mantlesupport.

In Figs. 2 and 3 the spring 10 is shown flared or of such size as tobrace against the ornament 6 instead of extending inside the latter, andthe spring or its upper part could be flared or widened, as desired, toextend up about the ornament a greater or less distance.

In the structure shown in the drawings the flange 11 forms a handle forrotating the valve or sleeve 19 for regulating the entrance of airthrough passages 20 into the Bunsen burner 2 for producing the requiredmixture of air and combustible.

The spring 10 is of suitable shape or size, strength, and material, soas to secure the required elasticity, and such spring can be leftexposed, as seen in Fig. 2, or more or less con cealed, as seen inFig. 1. In case of heavier lamps two or more springs 10 could be placedto coact. The spring or springs 10 will counteract such shocks orvibrations as caused, for example, by the rattling of a wagon in thestreet or by the vertical shocks arising in dancehalls, bowling-alleys,and the like. The portion 2 is connected to a bracket or supply-tube 15with stop-cock 16, and such connection may be either rigid or yielding.A second spring 17, Fig. 3, interposed between tube 2 and bracket 15,will allow or compensate for lateralmovementor vibration, while spring10 takes up vertical vibrations. The spring 17 is shown inclosed orsurrounded by a flexible or rubber coat or hollow ball 18, and thisspring 17 is sufficiently rigid to normally hold the burner l andmantle-carrier 9 upright while allowing slight lateral vibration. Thelateral vibrations taken up by spring 17 might be liable to arise, forexample, in such places as drill-rooms from a body of men marching orcoming suddenly from march to halt.

The ornament 6' in Fig. 1 can be omitted, if seen fit. The rubber tubeor elastic part 18 could be made su fflciently strong to vibratinglysupport the burner or mantle Without aid of spring 17; but the spring 17has been found to be serviceable.

WVha't I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the Bunsen burner 2 having the lateral flange 11,the upper burnersection 1 having a chimney-gallery 4, a perforatedcup-shaped ornament 6 depending from the gallery and a sleeve 1 1extending through the cup-shaped ornament and slidable vertically on theupper part of the Bunsen burner, a mantle-support mounted on thecup-shaped ornament, and a spring 10 resting at its lower end on saidlateral flange and yieldingly supporting the upper burner-section,substantially as described.

2. The combination of the Bunsen burner 2 having air-inlets 20 and thecup-shaped flange 11 surrounding said air-inlets, the upperburner-section 1 having the chimney-gallery 4, the perforated cup-shapedornament 6 depending from the gallery and the sleeve 14 extendingthrough the cup-shaped ornament and slidable vertically on the upperpart of the Bunsen burner, a mantle-support 9 mo unted on the cup-shapedornament, and a spring 10 resting at its lower end on said cup-shapedflange and yieldingly supporting the upper burner-section, substantiallyas described.

3. The combination of the Bunsen burner having a lateral flange 11, theupper burnersection 1 contracted to form the annularshoul der 14c andhaving the chimney-gallery 4, the perforated, cup-shaped ornament 6depending from the gallery and the sleeve 14: extending through thecup-shaped ornament and slidable vertically on the upper part of theBunsen burner,a mantle-support 9 mounted on the cup-shaped ornament, andthe spring 10 extending through the said cup-shaped ornament,surroundingsaid sliding sleeve and bearing at its ends, respectively, against saidannular shoulder and said lateral flange, substantiallyas and for thepurposes described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
